ROTO-CON® rotary converter provides smooth, reliable 3-phase power from single-phase lines. Best suited for operating motors that do not operate continuously at high load levels and for non-motor loads.
For the majority of applications, ROTO-CON® is sized to the largest 3Ø motor (based on FLA rating) or total motor HP to be operated at one time. For some applications, however, it is recommended that ROTO-CON be oversized to operate correctly. Type P comes in 240V input/output (Type 2P) and 480V input/output (Type 4P).
